PATENT JOHN F. LOOKE', OF RYE, NEYV HAMPSHIRE.

SPECIFICATION forming part of Letters Patent No. 365,830, dated July 5, 1887.

Application filed November 27,- 1886. Serial No. 220,633. (No model) To aZZ whom it may concern.-

Be itknown that I, JOHN F. LOCKE, of Rye, county of Rockingham, State of New Hampshire, have made certain new and useful Improvements in Brackets for Stages or Scaffolds, of which the following is a specification, taken n connection with the drawings accompanymg and forming a part hereof, in which Figure 1 is a side view of the bracket ap plied to the wall of a building, the wall and the securing-block of the braeketfastening being in section. Fig. 2 is a detail of the bracketpin detached. Figs. 3 and 4 are respectively a side and top view of the securing-block.

The object of my invention is the construe t on of a fastening by the use of which brackets such as carpenters use for supporting theirstaging or scaffolding in the erection of buildings may be more securely and easily fastened to the wall of the building, and the parts of which are less liable to be lost; and it consists in a pin adapted to be secured to the bracket so as to project from the vertical portion thereof, and having an enlarged head, and a slotted securing-block adapted to be passed over the headof the pin at one point and then to be moved on the pin, so as to bring the enlarged head thereof opposite the narrower part of the slot, thereby preventing the pin from leaving the block.

My invention is very simple, and will be readily understood from the following description and the accompanying drawings, throughout which like letters oforefcrence indicate like parts.

A represents the wall of a building or the object to which the bracket is to be secured.

K is a bracket of common form, to which the pin B is secured in a suitable manner, prefably by bolting or screwing the flattened shank portions a to the horizontal portion of the bracket, and allowing the body of theipin to pass through a hole in the vertical portion of the bracket, as shown. The portion of the pin which projects from the brack ct passes through the hole in the wall A to which the bracket is to be secured, and is provided with an enlarged head, 0, by means of which the securing-block D is held in place on the pin.

The head 0 may be either of larger diame ter than any other portion of the pin, or it may be of equal diameter with the body I) of the pin; and the part directly behind the head is flattened or cut away, as shown at d, Fig. 2,

in order to be received in the narrow portion of the slot f in the securing-block D.

The securin g-bl ock D is preferably of a wedge shape, being thicker at its upper end than at its lower end when in position, and is-provided lengthwise with a slot, f, which is enlarged at the lower or thin end of the block into a size suflicient to admit the head (3 of the pin,

slipped over the head of the pin, the head.

passing through the enlarged portion of the slot in the block, and the block is then passed downwardly, wedging the block firmly between Theslotfis of a size to admit the flat portion d of the head of the pin and the wall, the narrow portion of the slot receiving the narrow part (2 of the pin. The wedge shape of the block enables the bracket to be secured firmly .to different thicknesses, and the large bearingsurface of the block against the wall prevents the bracket from tearing out, as sometimes happens with the brackets in common use when the rough boarding of the building, to which the bracket is usually secured, is rotten or weak or in any way defective. The size and bearing-surface of the block D also clamp the bracket much more securely to the building than the small bearing-surface of the thumb nut which is screwed onto the end of the bracket-pin in brackets as now commonly constrncted. 7

Although, aslherctofore mentioned, a pin might be used having a round body,instead of the flat portion shown at cl, provided the head was enlarged, yet I deem the construction shown preferable, since the flat part (Z is received within the narrow portion of the slot f, and thus prevents the block from turning on the pin, otherwise there would be danger of 100 the block turning on the pin, then dropping down so as to bring the head of the pin opposite the enlarged portion of the slot, and thus 2.
